'L IMPROVEMENT IN TRUCKS FOR MOVING BUILDINGS.

Specification forming part of Letters Patent No. 196,289, dated October 23, 1877; application filed Aprn 9, 1877.

To all whom t may concern:

Be it known that I, WILLIAM BUsHEE, of Gloucester, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Rolls for Moving Buildings and other heavy weights, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to an improved roll.

` of buildings or other heavy weights, of a disk or plate adapted to be secured in a fixed posit-ion to the under side of abuilding or other object to be moved; a worm-wheel connected to said fixed plate by an axial bolt or shaft, about which it may be rotated in a horizontal plane; a worm-shaft for imparting such motion; a series of anti-friction balls or rolls interposed between said iixed and rotating plates; and a roll mounted in bearings in said rotating plate in a horizontal position, and adapted to bear upon and roll along the track prepared for the purpose, as will be explained.

Figure lis an inverted plan of my improved device. Fig. 2 is avertical section on line x a: on Fig. l. Fig. 3 is a similar section on line y gj on Fig. 1. Fig. 4 is a plan of the rotary plate, showing anti-friction balls; -and Fig. 5 is a partial section on line y y, Fig. l, illustrating a modification of theanti-friction device, in which a conical roll is substituted for the ball.

A is a circular plate, to be made, preferably, of cast-iron, made flat upon its upper side, and having formed in. its under side the shallow recesses a and b, and one or more semicircular annulargrooves, c c, and also provided with bolt-holes d d, through which and by means of lag-screw bolts, it may be secured firmly to the under side of the sill of a building, in an obvious manner.

B is another circular disk or plate, having its upper surface turned to fit the recesses a and b in the disk A, and having formed therein one or more semicircular annular grooves, e e, corresponding to c c in the disk A, and also having formed around its periphery a female screw, the threads j' extending across a groove, f', the bottom of which is in the form of a section of a circle when seen in cross-section, as in Figs. 2 and 3. g

The disk B is secured to the disk A by means of the axial bolt g and nut h, and takes its bearing upon the series of anti-friction balls z' t', as seen in Figs. 2' and 3, or upon the anti-friction conical rolls j, as seen in Fig. 5.

C is .aworm or screw shaft mounted in bearings k 7c, formed upon or 'secured to the disk A, and engaging, by its screw-thread, with the teeth f, formed in the edge of the disk B, as shown in Fig. l.

In the under side ofthe disk B is formed the recess or chamber l, within-which is placed the roll D, provided with the journals m m, fitted to and adapted to revolve in bearings formed in or secured to the disk B, with its periphery projecting a short distance below the lowest part of the disk B, as shown in Figs. 2 and 3.

The bearings for the journals m m consist of the removable half-boxes a u, made preferably of hard composition or tempered steel, and the caps o o, secured in place by the screws p p.

In moving buildings and other heavy weights as heretofore practiced, it has been customary to use a series of plain cylinders of wood or iron placed between the sills of the building, or the heavy timber shoes or skids generally placed beneath the building, and the track ot' timbers on which it is to move, without being directly secured to either, the building being moved upon such rolls till its rear end passes off from the rear roll, when said roll is carried to the forward end of the building and placed in position in advance of the other rolls, and so on, as fast as a roll is left in the rear bythe advance of the building, it must be carried forward and placed in a new position, all of which occasions a great deal of hard labor.

Again, if it is necessary to change the course of the building-as, for instance, such as turning the corner at the intersection of two streetsit becomes necessary to change the position of the Whole series of rolls Y :all be parallel to eaieli other, so as le roll Vin the saine direetionand preduce; tlie desired z 1 movement of the buildin g Without undue strain or frictionV i Y the rolls under the building, so that their axes shall all lie at right angles to the; neiv'course'.

V*This avery'laboriou's job, and besides itis a ver f difficult one to adjust Y Bytlieuse of'my :'unprovedV rolls theseob- 'eetions are entirely overcome, and the labor of moi/ing buildings and other Vlieavy Weights isgreatlyredueerb fi Y :The operation of my' improved roll isas fol i lows: If it desired'to move a building?V Vthe Y building is: raised and two or more heavy timlbersiare Vplaced ibeneatli its2 sills andi seeured thereto parallel to each other7 and' directly over atem'porar f Vtraek Vof :timbers laid upon Vthe ground in the usual? manner. 2 To the un- 'Y der side or" tlie'lieavytimbers ysecured to the sillsrof the building lare Vfirmly belted a suitable number of my improved rolls7 the bolts; passing biirouglrtlie rholes el din the 'disk A,' and y Y f screwed into the timber in aWell-knowninau-V ner.
